Does GlobalGAP certification promote agrifood exports?
研究了GlobalGAP认证对苹果、香蕉和葡萄出口的影响，发现认证促进贸易，但效果因产品和市场而异，且主要来自认证农场面积增长而非新认证生产者。
In global agricultural value-chains, private food standards are proliferating. Yet, their trade effects remain poorly understood. This paper assesses the effect of GlobalGAP certification on exports of apples, bananas and grapes. We estimate a structural gravity model using a global dataset of certified producers and the share of certified land area in total harvest area. While our results confirm GlobalGAP standards as catalysts to trade, we find that the trade-enhancing effect varies across products and destination markets. Furthermore, the trade effect is driven more by growth in the area of certified farms than by new certified producers.
